Why are toilet seats in public toilets shaped U-shaped?

You will see this pedestal sitting in the public toilet. What is the reason for this difference?

If you don't include . smells, there's a difference between when you walk into a public WC and sit on the toilet at home. The difference is: most of the public toilet seats are U-shaped, with a front opening. Meanwhile, household toilet or commercial center uses oval or round type.

U-shaped toilet seat.

But why is this difference? There are 2 reasons!

First , this stems from a US law in 1955 . Specifically, there are requirements in the Act: "All toilet seats, except those installed in the apartment, require a front opening, or an automatic opening and closing section".

The reason for this law is mainly because of sanitation. With U shape, you can sit comfortably without fear of sensitive areas to touch the toilet pedestal, thereby ensuring safety and hygiene issues for individuals, while preventing . mistaking urine on the pedestal .

The U-shaped platform is cheaper, because it uses less materials.

In addition, the U shape also helps women (and those who go "heavy") easier to clean. According to Lynne Simnick, vice president of the International Association of Mechanical Contractors (IAPMO), this toilet " allows women to clean up after going to the toilet without getting into the pedestal".

And the second is a purely economic problem, it's a cheaper U-shaped pedestal, because it uses less material.

Therefore, public buildings choose to use this type of platform, both ensuring hygiene and saving costs. Best of all!
